' rotated around said hub, in either direction,

T0 wZZ whom it may concern:

Be it known that LOHARLES SEY oLD, a citizen of the United States, residing at Oincinnati, in the county of Hamilton, State of Ohio, have invented certain Improvements in Presses, of which the following'is'a specification, reference being, had to the accompanying drawings, forming a part thereof.

My improved press is more especially designed for use in bookbinding establishments for pressing books to shape before finishing, but may be advantageously used in any other connection where it is desired to press paper or other articles to proper shape.

The object and nature of my invention will be apparent from the detailed description and claims hereinafter set forth.

In the accompanying drawingsz-Figure 1, is a view in elevation of my improved press, with one section of connecting pipe in-use. Fig. 2, is a vertical section through the hub of the hand-wheel and one side of said wheel, also the cap attached to lower end of screwrod, showing the preferred mode of pivoting the lever-bar socket in the rotatable box attached to the hub of said wheel. Fig. 3, is a top view of the hand-wheel, rotatable box and lever-bar socket. Fig. 4, is a top view of one of the weights for balancing the platen. Fig. 5, is a top view of a portion of one end of the platen, showing the positionof the eye thereon for guiding the platen. Fig. 6, is a view in elevation of one pipe connection to be used between the screw-rod and platen.

Myimproved press is preferablyconstructed as shown, and consists of a top cast portion A, and a base or bottom portion B, said top and bottom portions being connected by suitable stay-rods O, as shown. The stay-rods 0, (preferably three on each side) form a frame work for the support of the top plate, and screw-rod. The top plate A, is provided with a central screw-threaded opening in which the screw-rod D, operates. Near the lower end portion of the screw-rod is keyed the tral hub e, and anouter peripheral upturned flange e, as shown. In the top portion of this hand-wheel E, is the box receptacle F,

which has a collar encircling the hub e, in

. such a manner as to permit said box to be Serial No. 313,343. (No model.)

without rotating the wheel. In this rotatable box F, is pivoted the socket G, into which the lever-bar f, is placed, when desired to increase the pressure on the platen. The outer flange e of the hand-wheel E, is provided with the notches 6 for engaging the'leverbar. To the bottom portion of this hand wheel is cast or otherwise suitably secured the pins a to afford a hand-hold when desired to rotate the wheel by hand. I

- The platen H, is suspended betweenthe stay-rods O, by means of suitable chains or ropes 72., secured at one end to one of the ribs h, of the platen, and is then passed over suitable pulleys h secured in brackets attached t0 the top plate,the other end'of said chains or ropes being attached to the balancing weights lb The weights h are adapted to slide up and down the outerstay-rods, and

are retained in position thereto by means of the brackets 7L4, or equivalent device, secured to said weights. The platen is provided at each side with a central eye k which encircles the central stay-rods, as shown, to properly guide the platen. The central top portion of the platen is preferably countersunk to permit the end of the connecting piece I, to rest therein.

To the bottom end'portion of the screw-rod D, is secured the cap J, which is heldin place by screw-bolts passed through the shell of pipe or said cap, and engaging a circular groove in said screw-rod, as shown in Figs. 1 and 2, thus permitting said rod to rotate in said cap. The lower extension of this cap fits in the top of the connecting-pipeI,-tl1e outer flange of said cap bearingon the top of the pipe.

Having described the general construction of my improved press, I willnow describe its operation. When not-in use, the connecting pipe I, is removed, and the platen is left to swing at any desired height. Having placed the desired number of books, or other articles beneath the platen, the platen is pulled down onto said articles; and, if the height of the articles. be sufficient, no connecting pipe 01-1 piece need be used, as thecap J ,of the screwrod will rest in the countersunk portion of.

the platen, when pressure may be applied. When the height of books or other articlesis not sufficient to bring the screw-rod and platen IOO of the wheel.

into contact, a pipe of the desired length is placed in the top countersunk portion of the' platen,as shown,the cap J, of the screw-rod resting on the top of said pipe, after which the pressure is applied. The screw-rod may be lowered by hand so long as desired, by means of the pins 6 When desired to have additional pressure, the lever-barf, is placed in the socket G, and also in one of the notches e in the flange When the wheel has been rotated by means of the lever-bar as far as is practicable, said bar is elevated out of the notch(see Fig. 2) and with it the outer end of the socket G is elevated, the latter being pivoted in the rotatable box F. This box being free to rotate around the hub of the wheel, the said lever-bar, after having been raised out of the notch, is free to be swung back to. engage another notch in the flange of the wheel, without having to remove the bar from its socket. This latter feature of my invention may be advantageously applied to the ordinary forms of screw-presses in which the platen is connected direct to the screw-rod.

While it is preferred to use the pipe for making the detachable connection between the screw and platen, a solid piece of wood .or other material may be used if desired.

Two or more of these pipes or pieces accompany each press to accommodate varying heights of articles to be pressed.

It is preferred to use the aforedescribed mechanism for applying additional pressure in connection with the swinging platen; but, if desired, either feature may be used independent of the other.

The advantages of my improved press are apparent.

By reason of the swinging platen and connecting pipes of varying lengths, any desired height of books or other articles may be readily and quickly put to place, without the use of cumbersomeblocks or other articles which are inconvenient. Another advantage arises from the use of the rotatable socket in the pressure wheel, by means of which the lever-bar may be raised and turned back to engage in another notch in the flange of the pressure wheel, without removing said bar from the socket, thus saving much valuable time over the old method; in which the bar has to be removed from the socket every time the pressure wheel is partially rotated.

What I claim as new, and desire to secure by Letters-Patent, is

1. A press consisting of top plate A, bottom plate, B, stay-rods 0 connecting said plates, pressure-screw D operating within said top plate, platen H, counterbalanced by weights 77. and pipe I, the latter being adapted to connect said platen and screw, and suitable means for rotating said screw.

2. In a power press having a counterbalanced platen, the pressure-screw D having a hand-wheel E keyed thereto, and a detachable connecting pipe, I, substantially as set forth.

3. In a press having a pressure screw, the wheel E connected to said screw, said wheel having a peripheral upturned notched flange. e, and a socket, G,-rotatably and pivotally connected to the hub of said wheel, and lever f, substantially as set forth.

4. A press consisting of a pressure screw mounted upon a top plate, A, the latter being supported by stay-rods, 0, wheel E connected to said screw, the latter at its lower end having a detachable cap, J, and platen I-I, counterbalanced by weights h substantially as set forth.-

5. In a press having a pressure-screw, the wheel E connected to said screw, said wheel having an upturned flange c with notches e therein,box F rotatably connected to the hub of said wheel, socket G pivotally connected within said box, and lever fisubstantially as set forth.
